Sizing is strange

Verified Buyer Reviewed by Casual dresser from New York on Tuesday, March 22, 2016
This is a nice casual cardigan, but the sizing information on the STP site is a little misleading. I got this in a (UK) 10, thinking it would be small, but it turned out to be HUGE. I had also ordered another Barbour style in a (UK) size 12 and that turned out to be a much better fit. So not sure if the labelling is wrong, or the product info on the site?
